A represents the'window-frame or casing.

B is the window. C is the shade or curtain,

and D the roller or curtain-stick. This roller may contain, if desired, a spring and ratchet, sov as to operate automatically to roll up the curtain in any of the well-known ways in use. E E are two metallic slides furnishing bearings for the pivots of the roller.l F F are two metallic wires applied to the two sides of the window-frame, and strained tightly from brackets or pulleys H and J, and tighteninglevers G G, fastened to the window-frame at the four corners. These wires pass through holes in the slides E E', so that said slides may be moved readily up and down the wires, which thus act as guides. K K are cords to operate the curtain. These pass over pulleys H J, and raise and lower thelroller D upon the guide-wires. O O are metal pieces screwed, or otherwise irmly secured, toA the window-frame. P P are recesses in the lower ends of said pieces made so as to receive the ends of the tightening or straining levers Gr G ofthe wires F.

These wires are first secured to the pulley-frames H and J, secured to the upper corners of the window-frames and to the levers G before they are fastened in place. One end of the levers is 4then placed in the recesses P P, and the wires F strained by bringing the other ends of the levers down in place, as shown, Where they are permanently held by fastening them to the window-frame. It is necessary to have these wires strained tight.
